The current implementation of buildroot depe dependency graphing
either does forward- or reverse-dependency traversal.
This patch enables buildroot to graph forward and reverse dependencies
on the graph for the same package: (Diagram Credit: Yann E. MORIN)
$ make pkg-d-graph-both-depends
pkg A -. .-> pkg E
\ /
pkg B ----> pkg D ----> pkg F
/ \
pkg C -' '-> pkg G
In the above example a single graph shows pkg {A,B,C} are needed
by pkg D, and pkg D is a dependency of pkg {E,F,G}.
Makefile help and manual are also updated.

[Arnout:
- remove DEPTH and RDEPTH, their functionality is already covered by
BR2_GRAPH_DEPS_OPTS;
- remove --rdepth, it was felt to not add sufficient added value;
- add the new target to the manual;
- fix flake8 errors.

Although the asciidoc toolchain accepts any number of ~ to delimit a
listing block (i.e. a code block), it is actually specified to be
exactly four, i.e. ~~~~. Currently, a mix of diffrent numbers of ~ are
being used - sometimes even a different number at the beginning and at
the end of the block.
Normalize this to always use exactly four ~ for the delimiter.
